Ronaldo says he will do it just like he did after the 2006 World Cup.
The 24-year-old star told the Sun: “A part of the supporters show themselves to be more unhappy than others. But I hope to change their minds.
“When I put on the United shirt I give my maximum. Nobody can condemn me on this.
“I hope it will be similar to when I came back to England after the 2006 World Cup and I can win the fans back.”
Ronaldo insists it was his decision not to join Real Madrid in the summer.
He added: “Nobody can convince me about anything. Since I was young I’ve had to make decisions, I make them alone.
“I want to win more at this club. If the boss thinks I have to stay on the bench I respect that, even if it’s difficult.”
